BOOT OR SHOE TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 719,444, dated February3, 1903. Application filed February 23, 1899. Serial No. 706,563- (Nomodel.)

lo a, whom it may concern.-

Be it known that I, EDWIN E. ANGELL, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Boot or Shoe Trimming Machines, of which thefollowing is a specification.

This invention relates to improvements in the manufacture ofblade-holders for boot and \0 shoe machinery shown in the patent to A.S. Vose, No. 560,825, dated May 26, 1896, and especially shown in Figure9 of said patent; and the improvement consists in providing a largecontact-bearing for the means which holds the blade-holder in its properposition. The blade-holder shown in said Vose patent, Fig. 9, is held inits position by two retaining-fingers, and owing to the rotary andreciprocating motion of said cutter said fingers and also therecess wearaway rapidly, and it is to prevent this wearing that I have provided theconstruction shown in the drawings. In the accompanying drawings,whichillustrate aconstruction embodying my invention, Fig. 1 is a side viewof my improved extension-blade holder. Fig. 2 is an end view from theblade side. Fig. 3 is a sectional view. Fig. l is a plan view of theretaining-nut looking from the blade end. Fig. 5 is a sectional view ofthe retaining-nut. Fig. 6 is a detail perspective View of one of theblades. Fig. 7 is a side view, partly in section, of a part of themachine, showing my improvements applied thereto.

Like letters of reference refer to like parts throughout the severalviews.

A represents an extension-blade holder, to which is secured at one endat A the extension-blades A for feather-edging the bottom 0 of the bootor Shoe. B is a carrier upon said extension-blade holder, which engageswith a hole in the cutter-head in order to give revolution to saidextension-blade holder,as shown in Fig. 5 of said Vose patent; but Ihave only shown one in the present application, al-

though any number could be used for this purpose. The extension-bladeholder on its rear end is screw-threaded at O, and with said threadthere is adapted to engage the retaining-nut D, also internally threadedto engage the thread C at the end of the extension-blade holder A. Uponscrewing up the nut D its inner surface D contacts with the shoulder Con the extension-blade holder, thus locking the nut to theextension-blade holder and providing a wearing-surface D which contactswith the rear side of the sole-guard carrier, as shown in Fig. 3 ofPatent No. 688,815, granted December 17, 1901.

As shown in Fig. 7, the cutter G, of usual construction, is mounted onthe end of the shaft F, supported by the bearing E, one of which isshown in said figure, and over the cutter Gis located the cutter-guardH, mounted on the hub H, carried by the movable arm H and said guard iscapable of being removed from proximity to the cutter G when it isdesired to gain access to said cutter. The upper end of the carrier J,which corresponds to the carrier shown in my application filed February23, 1899, and having Serial No. 706,561, is provided with a hub J,around which is located the sole-guard holder K, provided with arms L,which carry on their extreme ends .the externally-threaded ring L, onwhich is located and adjustably secured thereto the internally-threadedringli/Larouud which is located the sole-guard N, having a lip N, whichfits into a Suitable recess in the adjustable ring M, and on said ringthe sole- 8o guard N is adapted to freely move.

The extension-blade holder A has considerable length and is journaled inthe elongated carrier-hub J. It is held therein by the fixed flange Jprojecting from one of its ends and engaging with an end of the hub, andthe nut D, turned on its other end and engaging with the other end ofthe hub. By removing the nutD the holder can be detached from thecarrier.

By this construction a lessnumber of parts is required and greaterdurability is obtained over the patent previously referred to.

I do not limit myself to the arrangement and construction shown, as thesame may be varied without departing from the spirit of my invention.

Having thus ascertained the nature of my invention and set forth aconstruction embodying the same, what I claim as new, and [O0 said hubwhereby the blade-holder is removably connected to the carrier.

In testimony whereof I have signed my name to this specification, in thepresence of :5 two subscribing Witnesses, this 15th day of February, A.D, 1899.
